In recent years, with the popularity of mobile products having camerafunctionalities, the demand of miniaturized photographing systems hasbeen increasing. The sensor of a conventional photographing system istypically a CCD (Charge-Coupled Device) or a CMOS (ComplementaryMetal-Oxide-Semiconductor) sensor. As the advanced semiconductormanufacturing technologies have allowed the pixel size of sensors to bereduced and compact photographing systems have gradually evolved towardthe field of higher megapixels, there is an increasing demand forcompact photographing systems featuring better image quality.

A conventional photographing system employed in a portable electronicproduct mainly adopts a four-element lens structure or a five-elementlens structure such as the ones disclosed in the U.S. Pat. No. 7,869,142and the U.S. Pat. No. 8,000,031. Due to the popularity of mobileproducts with high-end specifications, such as smart phones and PDAs(Personal Digital Assistants), the requirements for high resolution andimage quality of present compact photographing systems increasesignificantly. However, the conventional photographing system cannotsatisfy these requirements of the compact photographing systems.

Other conventional compact photographing systems with six-element lensstructure such as the one disclosed in the U.S. Publication No.2012/0314304 A1 enhance image quality and resolution. However, the shapeof the object-side surface of the fifth lens element cannot effectivelycontrol the angle at which the incident light projects onto an imagesensor from every field. Therefore, this photographing system tends toproduce more spherical aberration, coma aberration and astigmatism whichwill influence image quality.

DETAILED DESCRIPTION

An optical image capturing system includes, in order from an object sideto an image side, a first lens element, a second lens element, a thirdlens element, a fourth lens element, a fifth lens element and a sixthlens element. The optical image capturing system has a total of six lenselements with refractive power. The optical image capturing system canfurther include an image sensor located on an image plane.

The first lens element with positive refractive power has a convexobject-side surface, and can have a concave image-side surface.Therefore, the positive refractive power of the first lens element canbe adjusted for reducing the total track length of the optical imagecapturing system.

The second lens element can have negative refractive power, a convexobject-side surface and a concave image-side surface. Therefore, it isfavorable for correcting the aberration generated from the first lenselement. Furthermore, the surface shape of the second lens element isfavorable for correcting the astigmatism.

The third lens element can have positive refractive power and a conveximage-side surface, so that the positive refractive power of the firstlens element can be evenly distributed so as to prevent the sphericalaberration from being excessively large, and thereby thephotosensitivity of the optical image capturing system is reducedeffectively.

The fourth lens element with negative refractive power has a concaveobject-side surface and a convex image-side surface, so that thatastigmatism and the Petzval Sum of the optical image capturing systemcan be favorably corrected so as to make the image plane more flat.

The fifth lens element with positive refractive power has a convexobject-side surface, and can have a concave image-side surface. Thefifth lens element has at least one inflection point on at least one ofthe object-side surface and the image-side surface thereof. Therefore,the angle at which the incident light projects onto the image sensorfrom every field can be effectively regulated. It is also favorable forreducing the spherical aberration and correcting the coma aberration aswell as the astigmatism of the off-axis.

The sixth lens element with negative refractive power has a concaveobject-side surface, and can have a concave image-side surface.Therefore, the principal point of the optical image capturing system canbe positioned away from the image plane so as to reduce the back focallength to keep the optical image capturing system compact. Furthermore,the sixth lens element has at least one inflection point on at least oneof the object-side surface and the image-side surface thereof. It isfavorable for effectively reducing the angle at which the incident lightprojects onto the image sensor from the off-axis so as to correct theaberration of the off-axis.

When a curvature radius of the object-side surface of the fifth lenselement is R9, and a curvature radius of the image-side surface of thefifth lens element is R10, the following relationship is satisfied:0<R9/|R10|<2.3. Therefore, the optical image capturing system isfavorable for better adjusting the light path so as to improve imagequality. Preferably, the following relationship is satisfied:0<R9/|R10|<1.5. More preferably, the following relationship issatisfied: 0<R9/|R10|<0.8.

When a central thickness of the third lens element is CT3, and a centralthickness of the fourth lens element is CT4, the following relationshipis satisfied: 0.1<CT4/CT3<1.3. By such an arrangement, the thickness ofthe lens elements is thereby favorable for preventing the lens elementsfrom being deformed.

When an axial distance between the fourth lens element and the fifthlens element is T45, and an axial distance between the fifth lenselement and the sixth lens element is T56, the following relationship issatisfied: 0<T45/T56<0.2. Therefore, it is favorable for assembling thelens elements so as to increase the manufacturing yield rate.

When a curvature radius of the object-side surface of the fourth lenselement is R7, and a curvature radius of the image-side surface of thefourth lens element is R8, the following relationship is satisfied:−0.4<(R7−R8)/(R7+R8)<−0.1. Therefore, it is favorable for correcting theastigmatism of the optical image capturing system.

When a focal length of the second lens element is f2, and a focal lengthof the sixth lens element is f6, the following relationship issatisfied: 0.40<f6/f2<0.85. Therefore, it is favorable for correctingthe aberration of the optical image capturing system so as toeffectively reduce the total track length.

When a distance in parallel with an optical axis from an axial vertex onthe object-side surface of the sixth lens element to a maximum effectivediameter position on the object-side surface of the sixth lens elementis Sag61 (When the distance towards the image side of the optical imagecapturing system is positive, and when the distance towards the objectside of the optical image capturing system is negative.), and a centralthickness of the sixth lens element is CT6, the following relationshipis satisfied: −3.2<Sag61/CT6<−1.0. Therefore, it is favorable formanufacturing and shaping the lens elements so as to effectively keepthe optical image capturing system compact.

When a vertical distance between a non-axial critical point on theobject-side surface of the fifth lens element and an optical axis isYc51, and a vertical distance between a non-axial critical point on theimage-side surface of the fifth lens element and the optical axis isYc52, the following relationship is satisfied: 0.5<Yc51/Yc52<1.5.Therefore, it is favorable for correcting the aberration of theoff-axis.

When a curvature radius of the object-side surface of the second lenselement is R3, and a curvature radius of the image-side surface of thesecond lens element is R4, the following relationship is satisfied:0.10<(R3−R4)/(R3+R4)<0.55. Therefore, it is favorable for correcting theastigmatism of the optical image capturing system.

When a curvature radius of the object-side surface of the sixth lenselement is R11, and a curvature radius of the image-side surface of thesixth lens element is R12, the following relationship is satisfied:−1.2<R11/R12<0.2. Therefore, it is favorable for reducing the back focallength of the optical image capturing system so as to keep the systemcompact.

When an Abbe number of the fourth lens element is V4, and an Abbe numberof the fifth lens element is V5, the following relationship issatisfied: 0.2<V4/V5<0.6. Therefore, the chromatic aberration of theoptical image capturing system can be corrected.

When a focal length of the first lens element is f1, and a focal lengthof the fifth lens element is f5, the following relationship issatisfied: 0.6<f1/f5<1.1. Therefore, it is favorable for reducing thesensitivity of the optical image capturing system.

The optical image capturing system can further include the image sensorlocated on the image plane. When an axial distance between theobject-side surface of the first lens element and the image plane is TL,and a maximum image height of the optical image capturing system (halfof a diagonal length of an effective photosensitive area of the imagesensor) is ImgH, the following relationship is satisfied: TL/ImgH<1.75.Therefore, it is favorable for keeping the optical image capturingsystem compact so as to be applied to portable electronic products.

According to the optical image capturing system of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of glass material, thedistribution of the refractive power of the optical image capturingsystem may be more flexible to design. When the lens elements are madeof plastic material, the manufacturing cost can be effectively reduced.Furthermore, the surface of each lens element can be aspheric, so thatit is easier to make the surface into non-spherical shapes. As a result,more controllable variables are obtained, and the aberration is reduced,as well as the number of required lens elements can be reduced whileconstructing an optical image capturing system. The total track lengthof the optical image capturing system can thereby be reduced.

According to the optical image capturing system of the presentdisclosure, when the lens element has a convex surface, it indicatesthat the surface is convex at the paraxial region; and when the lenselement has a concave surface, it indicates that the surface is concaveat the paraxial region.

According to the optical image capturing system of the presentdisclosure, there can be at least one stop provided, such as an aperturestop, a glare stop, or a field stop. Said glare stop or said field stopis allocated for reducing the stray light and thereby improving theimage resolution thereof.

Furthermore, an aperture stop can be configured as a front stop or amiddle stop. A front stop disposed between the object and the first lenselement can provide a longer distance from an exit pupil of the systemto an image plane and thereby the generated telecentric effect improvesthe image-sensing efficiency of an image sensor. A middle stop disposedbetween the first lens element and the image plane is favorable forenlarging the field of view of the system and thereby provides a widerfield of view for the same.

According to the optical image capturing system of the presentdisclosure, a critical point is a non-axial point of the lens surfacewhere its tangent is perpendicular to the optical axis.

According to the optical image capturing system of the presentdisclosure, the optical image capturing system is featured with goodcorrection ability and high image quality, and can be applied to 3D(three-dimensional) image capturing applications, in products such asdigital cameras, mobile devices and tablets.
